How to Install an Electric Tankless Water Heater

Water heaters are essential equipment in everyone’s home, especially in monsoon season. Tankless water heaters are replacing traditional water heaters as technology progresses. A tankless water heater will save your time, space, and money. It’s essential to properly How To Install an Electric Tankless Water Heater if you want it to last longer.

Where Should I Install It? 

The first step is finding a suitable wall to put the water heater on. It makes sense to locate an entire house water heater near the hottest water is consumed. Once you open a faucet, it will allow you to get hot water quickly. You must also have a connection to the entire cold water line every time. 

On the other hand, electric tankless water heaters do not require venting. You can also select a place where a tank-based water heater might not fit, such as a tiny bathroom or even under basins, as you will not have a storage tank. But the important factor is electric tankless water heaters must be mounted vertically, with the water and electricity supply connections facing downward.

You could avoid where your tankless electric water heater would get splashed with water or other contaminants. Avoid the places the temperature will drop below freezing.

How to Install an Electric Tankless Water Heater

Note: Remember that this assembly instruction is intended to serve as an example. The methods to set up the water heater may differ depending on your model. As a result, be careful to read the complete product manual.

Step 1: 

Turn off all circuit breakers involved, and the primary water supply should be turned off.

Step 2:

Remove any bolts that hold the unit’s front cover before installing it. Take the front cover. Single or more plugs may need to be removed before you can lay them aside.

Step 3:

The electric tankless water heater should be mounted on the wall.

Step 4:

Now, you can connect the cool and hot water lines. It’s generally more accessible with a stainless steel flex pipe with a 34″ diameter and Teflon tape. However, copper or PEX tubing could be used. Water heaters have a filter screen at the cool water entrance that needs to be cleaned regularly. That’s why the cold water connections must be disconnected quickly. If you really must cut into a pipe, make sure the edges are clean. Remember to cleanse the pipes before attaching them to the heater when soldering, and that too much heat can harm the device.

Note: If the receiving water pressure surpasses a specific threshold, now it is the time to fix a pressure reduction valve just on the cooling side. Unless local or state installation requirements mandate it, a T&P has to be fitted on the hot water side – should not be necessary.

Step 5:

To expel any air from either the pipes or the water heater, open various hot water for a few minutes. In the meantime, inspect all connections for leakage. Close all electrical outlets.

Step 6:

Connect the tankless water heater to the electrical panel on the single side and the electrical panel on the other side. Read the manufacturer’s instructions for the appropriate wire and circuit breaker size and number. Small units, for instance, could be applied to a specific circuit by using a pair of 6/2 AWG wires and a 50A dual pole breaker to safeguard the ground. Larger devices may require different circuits, as well as thicker cables. Reduce every wire set to length and strip it, then pass it through the bottom slots of the heater housing and secure it in the terminal block’s corresponding slots. A ground conductor should be connected to the unit’s grounded busbar and the circuit protection panel for every circuit.

Step 7:

Every electrical connection should be double-checked. Ensure the various wire sets aren’t mixed. Replace the front cover of the machine.

Step 8:

Circuit breakers have to turn on. Now is the time to turn on the electric tankless water heater. Set it up as per your needs, such as altering the temperature of the water to your comfort.

Step 9:

urn on a hot water faucet. Wait till the temperature has returned to normal. Check the temperature and make any necessary adjustments.

Tips:

Set a shut-off valve before and after the machine so you may switch off the supply of water to the unit for servicing or other reasons without shutting off the supply of water to the remaining places in your home.

Final Words:

After buying the electric tankless water heater, an essential element is to install the electric tankless water heater properly. With the help of our guide, we hope you can easily install the water heater.
